Side hustlers are seemingly everywhere - some surveys suggest they account for around half of UK workers - and stories of getting rich quick and abandoning the 9-5 are plenty. But the reality for many is much less glamorous: long hours; a precarious balancing act with the day job; and a good chance of failure. Evan Davis speaks to side hustlers, and their employers, to find out what it’s really like balancing two jobs at once. Plus, why is side hustling so popular anyway? Does it reveal a flourishing entrepreneurial spirit in the UK, particularly among young workers, or is it a symptom of a changing relationship between employer and employee?Evan is joined by:Julian Douglas, global CEO, VCCP; Ewen MacPherson, chief people officer, Havas UK; Karen Burke, founder, Go Goosey.
